M64 - Black Eye Galaxy

The Black Eye Galaxy (also known as the "Evil Eye" , or "Sleeping Beauty" galaxy) is a complex and unusual spiral galaxy 17 million light years away. M64's distinctive characteristic is the thick band of obscuring dust which darkens its central nucleus, giving the clear impression of a massive cosmic eye. What makes M64 so odd is the fact that the gas and stars in the outer bands of the galaxy counter-rotate with respect to those in the inner area. Astronomers believe that this phenomenon is the result of a violent collision with a smaller galaxy over a billion years ago, leading to its absorption and the merging of the two galaxies.

This image was captured in late April, and is a stacked image from 100 sixty-second subexposures. I'm finally getting around to processing some data from March and April. Was hoping to get some more data, but galaxy season is flying by fast, and the weather hasn't been favorable.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
